| Zusammenfassung | Detectors based on single crystal synthetic diamond show promise as neutron spectrometers for the ITER project. In this work, the stability of the response function of two diamond detectors was tested at the Physikalisch-Technische Bundesanstalt (PTB) accelerator using a 14 MeV neutron field and a method of time-resolved fluence monitoring. In addition, measurements at the PTB ion-microbeam were made to investigate the charge collection properties of the detectors in more detail. The 12C(n,α)9Be peak response of one of the detectors was found to be stable within 1% after irradiation with a neutron fluence of 8 × 109 cm-2. The absolute value of the peak response of this detector was determined as 8.65(26) × 10-5 cm². |
